OCCI StatelessConnectionPool DestroyMode::SPD_FORCE usage scenario

OCCI version: 11.2
OS environment: SUSE Linux Enterprise Server 11 SP2
Oracle database: Oracle 11g R2
Previously I use default option to terminalConectionPool by "envirnoment->terminateStatelessConnectionPool(pool)", but if there is a busy connection and at the same time the NIC is disabled by shell command "ifconfig eth0 down", the error "ORA-24422" is thrown.
Now I need to shutdown all connections forcefully by using DestroyMode::SPD_FORCE, but according the document, it says "SPD_FORCE indicates that any busy connections in the pool are forcefully terminated and the pool is destroyed; the user loses memory corresponding to the number of connections forcefully terminated."
Does the "loses memory" means "memory leak"? In application or in OCCI library?
Is anybody knows the background, please help!!
Thanks in advance.

  • Establish setting 'profiles' for different usage scenarios?

    I'm wanting to easily switch between different settings presets (for example, when I connect my laptop to my TV via HDMI, I'd like to have the energy settings set to "never go to sleep". -- Currently I'm having to manually adjust these settings back and forth each time I want to change them).
    I'm looking for a way to establish profiles like this for different usage scenarios -- something that allows a quick menu selection or key combo to toggle the presets.
    Anyone have any ideas?

    Thanks for the link. It looks like that app would do what I wanted.. However it may not be properly functional with 10.6, as it doesn't actually manage to change any settings (though it thinks it has) when switching locations.
    I've emailed the support at Centrix, makers of NetworkLocation (paid application, looks like it's still actively developed) to see if it would allow me to change energy saver settings.

  • Usage scenarios of CacheFactory and DefaultCacheServer

    What kind of usage scenarios of CacheFactory and DefaultCacheServer exist? What is the best for start server and what for start members? Thank you.

    Hi,
    CacheFactory is used to obtain an instance of a cache and DefaultCacheServer is used to start all services that are declared as "autostart" in configuration. CacheFactory should be used when you need to introspect the cache and for all other purposes it should be DefaultCacheServer.
    What is the best for start server and what for start members : DefaultCacheServer
    Hope this helps!

  • Proper use of ConnectionPool in occi

    Hi,
    I am developing a client server application using Windows server 2003 x64, Oracle 11.1.0.6.0 client connecting to oracle 10.1.0.2.0 database, Visual studio 2008, visual c++ 9.
    The scenario is something like this,
    upon receiving the client request, the server executes a stored procedure as per the request. I have a number of classes thru which the stored procedure gets called. Currently, in every method of these classes, I am creating new connection to the database as follows..
    +Environment *env = Environment::createEnvironment(Environment::OBJECT);+
    +Connection *conn = env->createConnection( USERID, PASSWORD, ORACLESID );+
    But now I want to use a ConnectionPool to improve performance of the application.
    My question is, where do I create the ConnectionPool object so that it is accessible from all the methods of the classes?

    Got it!!
    I did the following..
    Declare the Environment and StatelessConnectionPool objects above main function.
    +oracle::occi::Environment *env;+
    +oracle::occi::StatelessConnectionPool *connPool;+
    +int tmain(int argc, TCHAR* argv[])+
    +{+
    +......+
    +}+
    Then declare these objects as EXTERN from wherever you want to access them.
    +extern oracle::occi::Environment *env;+
    +extern oracle::occi::StatelessConnectionPool *connPool;+
    +//Method that uses these objects+
    The objects can directly be used in the methods where the they are declared as 'extern'.
    Enjoy!

  • Multiple usage of Source System is not possible with installed DMIS version on source

    Hello folks!
    I`ve got a problem trying to adjust the Data Replication to SAP BW (on HANA) using SAP LT Replication Server.
    I`ve deleted one connection and after that I`m trying to create new one through  Configuration & Monitoring Dashboard (transaction LTR) with the same source / target systems.
    As result when on the second step (Specify Source System) I specify RFC destination of the source system it appears an error with text
    "Multiple usage of Source System is not possible with installed DMIS version on source".
    But there`s no any adjusted connection in system now..
    Please, help me to understand  how to fix that problem, I can`t find a solution

    Hi,
    When you say that you 'deleted one connection', did you delete the RFC connection or the SLT Configuration? If it is not a real multiple usage scenario, then deactivate the 'allow multiple usage' flag, else install the correct DMIS version on both SLT and source.
    Thanks

  • JDBC Adapter in async. scenario

    Hi everybody.
    I have the following scenario:
    R/3  --->  XI ---> Legacy
    In this scenario, there is at the moment a synchronous call from XI -> Legacy using the JDBC receiver adapter. In this call there are various SELECTs and UPDATEs, so I have to use the XML SQL format of the JDBC receiver adapter.
    Unfortunately, the processing of the synchronous call is quite slow, and from time to time there even is a timeout which aborts the whole process. In order to get this process to work I only see two solutions:
    a) increase the timeout values of the synchronous call
    b) switch from synchronous to asynchronous processing
    I don't like solution a) because it could possibly influence others aspects of our XI system as well, so I prefer b).
    However, I do not know how to do it or even if it is possible at all...
    Is it possible to split up the synchronous call in an asynchronous request/response pair and to use correlation in a BPM?
    Is JDBC receiver adapter capable of this usage scenario?
    Regards, Joerg

    Hi everyone!
    Thanks for the valuable input.
    Alas, I still have a problem...
    I did the following: I inserted a dummy SQL statement into my request XML message. This dummy statement simply inserted an ID into the SELECT, and this ID is returned "as is" in the result. I use this ID to create a correlation between an asynchronous SEND step in my BPM and an asynchronous RECEIVE step in the same BPM. Unfortunately it seems to me that the JDBC adapter is not capable of working in an asynchronous mode. I have created a receiver adapter, I send my SQL XML message - and I get <i>no</i> return. It seems to me like the response message (my SQL XML should generate a response) "vanishes" - there is no answer...
    Is there some kind of "trick" I have to apply in order to get the JDBC receiver adapter to work in this scenario?
    Regards, Joerg

  • Experiences on first usage of Oracle SQL Developer Data Modeling

    Hi @ll,
    working with Quest Toad Data Modeler 2.25 over a year, I'm searching for a replacement with the ability to create ALTER TABLE... statements. Today I downloaded the standalone version and tried to compare my local database against our develoment server.
    Our usage scenario is that the development database can be changed by each developer. We have a trigger activated for monitoring (and logging) database changes. Currently the tested and released changes will be merged into the Toad data model manually by me.
    Using the Toad model, we create DDL scripts for the SAP supported databases: Oracle, MaxDB, MS-SQL and DB2.
    I'd like to facilitate this process.
    h3. Test 1
    1. Import the current model from the development database (User A), save it as XML
    2. Import the current model from my local database (User B), save it as XML
    3. Compare the XML models
    h4. Results
    a) each table is displayed as modified, although no difference is displayed in any column
    b) in the DDL, source tables are renamed with a "bcp_" prefix
    c) for NVARCHAR2, data types are changed (length from 756 to 510, 1800 to 1200)
    h3. Test 2
    1. Import the current model from the development database (User A), save it as XML
    3. Compare the imported model with the XML
    h4. Results 2
    a) The field attribute "Mandatory" changed from "true" to "false"
    h3. Test 3
    1. Import from database
    2. Compare against a XML scheme
    h4. Results 3
    a) Comparing shows the modified tables only - this works nearyl as expected
    b) still different length for datatype NVARCHAR2
    h3. Wish List
    a) the Open File dialog always opens in "My Files", better would be the last opened directory
    b) While starting the comparing, allow changing "source" and "target"
    c) Allow comparing two database schemes
    d) Support for MaxDB?
    Overall, this new tool looks very promising and I'm looking forward to testing the next versions ;-)

    Hi Christian,
    thanks for trying Oracle Data Modeling.
    EAR2 is released and NVarchar2 problem is fixed there. Also are fixed some problems related to your area of interest - applying differences to database.
    On your observations:
    1) each table is displayed as modified, although no difference is displayed in any column - column ordering could be changed, or some of table properties - you can check this by clicking on table node and you can look at details tab for more information
    2) in the DDL, source tables are renamed with a "bcp_" prefix - this is typical rename, create, copy pattern for applying changes that require restructuring of table and intermediate preserving of content. If it's not enough you can try "Advanced DDL" option which gives more control over the whole process - self controlled script with logging, restarting, execution window, error masking. You have option to unload table into file system and load it back after original table is recreated (LOB columns are not supported - we can add support if there is demand for that). Transformation function can be defined for columns with changed data type. There are few words about that in "Data Modeling overview" document (p.15) - http://www.oracle.com/technology/products/database/sql_developer/pdf/sqldeveloperdatamodelingoverview.pdf

  • Memory leak in OCCI/libclnts on Linux RHEL 5.5 ? Please advise...

    Hi all,
    Starting with some background:
    I have an application that has been running on 32-bit Linux server for years without problem, a few weeks ago it was ported to 64-bit RHEL 5.5 (compiled with -m32). Now with the application in the new environment some processes are growing in memorysize.

    There has been quite a few changes due to the new server. New compiler (gcc) from version 2.96 to 4.1.2, new version of oracle client 10g to 11g (11.2.0.2), new version of OCCI (also 11.2.0.2). The applications sourcecode is pretty much unchanged though, and that is why I turn to all of you for help.
    Is there anyone who knows anything about this problem and how to even start to fix this leak (if it even is in OCCI)?
    I can supply sourcecode and/or logs if needed. It is quite a lot of complex code so it might take me a while to sort out the relevant code though...

    Thanks for your input! Tough this post is from some time ago this is still an issue for me I'm afraid, so I appreciate all the help I can get.
    I have stripped down the code to just the basic functions needed to replicate the problem. The pool creation and connections are the same as in our application (which is unchanged since before the porting). Though the following code makes no indications of a leak when run through Valgrind, it still grows when checked in "top". It could be that I stripped the code too much, but this is pretty much what our application does. It creates a database lock (not in this code), creates connection, (read table), terminates connection and release lock every 6 seconds to check if there is any new assignments added...
    #include <iostream>
    #include <string>
    #include <occi.h>
    using namespace oracle::occi;
    using namespace std;
    Environment *env;
    ConnectionPool *connPool;
    Connection *con;
    int x, loopnr;
    string usr = "test_user";
    string pwd = "test_pw";
    string url = "dbtest";
    void run(int x) { // Run loops
    for(int i=0; i<x; i++){ // Loop connect and disconnect x number of times
    try {
    fflush(stdout); // Update console row for count value
    con = connPool->createConnection (usr, pwd); // Connect
    usleep(100000);
    connPool->terminateConnection (con); // Disconnect
    cout << "\r"; // Update console row for count value
    cout << loopnr << endl; // Print number of loops done
    usleep(100000);
    loopnr++; // Count number of loops done
    catch(SQLException ex) { // Exception handling
    cout<<"SQLException"<<endl;
    cout<<"Error number: "<< ex.getErrorCode() << endl;
    cout<<ex.getMessage() << endl;
    int main(int argc,char* argv[]) {
    cout << "IN --- main()\n";
    if(argc == 2) { // Read number of loops as argument...
    x = atoi(argv[1]);
    else { // ...or run loop 200 times if no args
    x = 200;
    try{
    env = Environment::createEnvironment (Environment::DEFAULT); // Create environment
    loopnr = 1;
    connPool = env->createConnectionPool(usr, pwd, url, 1, 2, 1); // Create pool
    run(x); // Run loops
    catch(SQLException ex) { // Exception handling
    cout<<"SQLException"<<endl;
    cout<<"Error number: "<< ex.getErrorCode() << endl;
    cout<<ex.getMessage() << endl;
    env->terminateConnectionPool (connPool); // Cleanup Pool when done
    Environment::terminateEnvironment (env); // Cleanup Environment when done
    cout << "\nUT --- main()\n";
    return 0;
    Above code is built with the following makefile:
    ORACLE_HOME=/opt/oracle/product/32bit-client-11.2.0.2
    CXXFLAGS = -Wall -m32 -g -fPIC \
    -I$(ORACLE_HOME)/rdbms/public
    LDLIBS = -L$(ORACLE_HOME)/lib/ -locci \
    -L$(ORACLE_HOME)/rdbms/lib/ -lclntsh
    LDFLAGS = -m32
    default: all
    Sample: Sample.cc
    all: Sample
    clean:
    rm -f Sample *.o
    Hopefully someone can make sense out of this....

  • SQL Server 2012 - RESOURCE MONITOR / PREEMPTIVE_XE_CALLBACKEXECUTE high CPU usage

    Hello, 
      We are currently in the process of migrating an existing clustered SQL Server 2008 R2 instance over to a clustered SQL Server 2012 instance as we phase out the Windows Server 2008 with SQL Server 2008 R2.
      The setup is identical for the SQL Server 2012 instance as it is on the SQL Server 2008 R2 instance.  (meaning the RAM and CPU are both the same or better on the SQL Server 2012 instance)
      The process in which we are migrating is that we're moving a few databases over to the new SQL Server 2012 instance each night.  What we've noticed is that the CPU usage is much higher on the SQL Server 2012 instance than on the previous
    SQL Server 2008 R2 instance even though the there is only 1/2 of the databases migrated to the 2012 instance. 
      Running the following script:
    ;with cte ([totalCPU]) as (select sum(cpu) from master.dbo.sysprocesses)
    select
    tblSysprocess.spid
    , tblSysprocess.cpu
    , CONVERT(BIGINT,(tblSysprocess.cpu * CONVERT(BIGINT,100))) / CONVERT(BIGINT, cte.totalCPU) as [percentileCPU]
    , tblSysprocess.physical_io
    , tblSysprocess.memusage
    , tblSysprocess.cmd
    , tblSysProcess.lastwaittype
    from master.dbo.sysprocesses tblSysprocess
    cross apply cte
    order by tblSysprocess.cpu desc
    Produces the following results:
    In a clustered environment, is this normal and if not, does anyone know what this means or how to reduce the CPU usage?
    Thanks.

    Hello,
    The following query may help us identify extended events or audit configurations running on that SQL Server server that are producing that high CPU usage scenario.

  • License Usage on CWMS Version1.5 - 50 Port Deployment without IRP

    I am not able to understand how the license usage is being accounted in CWMS 1.5.
    Currently  I have deployed CWMS - 50 Port without IRP. The CWMS 1.5 is integrated  with CUCM 7.X. There are 3 hosts configured on the system and the  license count is increasing for every meeting that is scheduled. The  license count increases only when the first participants joins the  meeting.
    I have tested a few scenarios -
    1.  I have hosted a meeting and I joined only the teleconference, Other  participants joined the meeting and the license count increased by '1'
    2.  I have hosted another meeting at a different time and did not join the  meeting. Other participants joined the meeting and the license count  increased by '1'
    Please Note - In both scenarios the Atendees Join before host option was checked.
    I am currently refering the licenses usage scenarios posted on Cisco and has not found any resemblance.
    http://www.cisco.com/en/US/docs/collaboration/CWMS/b_planningGuide_chapter_0111.html
    Request your help in clarifying how the license usage counts increment.
    Thank you.

    Hi Joseph and Benjamin,
    I am not sure whether you have got the answer for this already, anyway, here is the explanation.
    There is a defect opened for incorrect license count shown in the CWMS dashboard. You can check the defect details in the link below,
    https://tools.cisco.com/bugsearch/bug/CSCul57521
    Our development team analyzed the above defect and identified the root cause of this issue as another defect. The defect details can be seen in the link below,
    https://tools.cisco.com/bugsearch/bug/CSCul03486
    To summarize the above two defects, sometimes, the telephonic session in CWMS doesn't end correctly and stays active through out. Hence, all the meeting initiated by this user will have one simultaenous meeting always. This is the reason, for licensing count getting increased even the meeting is scheduled in different date and time.
    Let me know if you need any further details.
    Regards,
    Hari

  • DID YOU KNOW?? - ABOUT ADVANCED COMPONENTS IN THE PALETTE??

    <br>
    Hi All,
    DID YOU KNOW??
    The IDE ships with the following Advanced Components in the Palette.
    These advanced components are a set of JavaServer Page markup tags for advanced users. The components have no visual appearance and are useful to developers with experience in JSP and JavaServer Faces technologies.
    * Encoding
    * Faces Action Listener
    * Faces Converter
    * Faces Validator
    * Faces Value Change Listener
    * Faces Verbatim
    * Link
    * Load Bundle
    * Markup
    * Meta
    * Parameter
    * Script
    Lets look at MARKUP component in more detail.
    The MARKUP Component
    You can drag the Markup component Markup component icon from the Palette's Advanced category to the Visual Designer to create a standard HTML tag. The Markup component enables you to insert HTML elements into the JSP page in places that HTML is not permitted.
    When you drop this component on a page in the Visual Designer, you cannot see it on the page until you set the tag property. You can see it in the Outline window and you can select it there to edit its properties in the Properties window.
    Use the tag property to specify the type of HTML element to insert. For instance, to insert an <hr> tag, set the tag property to hr with no angle brackets and select the singleton property .
    To provide compliance with XHTML, if the HTML element you are inserting is a singleton element, you must specify the singleton property, which causes a trailing /> to be generated in the rendered HTML. For example, the <br> element is a singleton element that must be rendered as
    to make it XHTML compliant.
    If you want to specify HTML attributes in addition to id and style for the element you are inserting, use the extraAttributes property.

  • DID YOU KNOW?? - ABOUT DATAPROVIDER COMPONENTS IN THE PALETTE??

    Hi All,
    DID YOU KNOW??
    Practically all applications entail accessing data of some sort, often data stored in a relational database table or some sort of list, such as a vector or an array. Usually you need to read in data from the data source, but many times you have to update that data, too. The Sun Java Studio Creator integrated development environment, as another enhancement to its application model, provides data provider components that simplify accessing data sources, regardless of whether the data source is a relational database table, flat file, web service, vector, array, or some other type of data store.
    A data provider component is a nonvisual abstraction for wrapping sources of data, and it represents a more generic and flexible data binding mechanism. A glance at the Palette indicates that there are many different kinds of data providers available to you. These include data providers for cached RowSets, ResultSets, lists, arrays, maps, table rows, and method results.
    These data providers constitute a layer between a web application's components and its persistence tier, such as a database table, Array object, or Enterprise JavaBean object. This layer enables you to access data in a consistent way, even though data may come from different sources.
    Lets briefly discuss the CachedRowSetDataProvider
    The CachedRowSetDataProvider Component
    A CachedRowSetDataProvider is a wrapper to data held in a CachedRowSet. The primary purpose of a CachedRowSetDataProvider is to facilitate binding to components in the IDE. A CachedRowSet stores the data retrieved from a database. In fact, the only information held by the CachedRowSetDataProvider is a cursor position into the CachedRowSet. Multiple CachedRowSetDataProvider instances can reference the same CachedRowSet, and each instance will have its own cursor position into the CachedRowSet.

  • Venue 11 Pro - Slim Keyboard not behaving as expected or it should.

    I recently received the slim keyboard from dell for my Venue 11 Pro - Baytrail tablet.    Overall I like the quality and functionality, although I too like others have encountered the intermittent non-functional keyboard, but that's not the subject of this post.
    I have noticed a couple items in its behavior that don't work as you would expect and I hope can be corrected via software. 
    1. When the keyboard is attached but folded back behind the tablet (ie the keyboard is not in use) the on screen keyboard will not appear.  This makes it hard to use the device as a tablet as anytime data entry is required you need to unfold the keyboard and hold it somehow while you type then fold it back behind the screen to continue tablet use.   When folding the keyboard behind the unit its just as important to make the on screen keyboard available as it is to stop the keyboard itself from functioning,  right now the keyboard stops working as it should be no alternative input is available. 
    2. In much the same way as item #1.  When the keyboard is attached but folded back behind the tablet orientation is locked so the screen will not rotate to portrait or landscape mode at need.  So if you were carrying it with the cover / slim keyboard on and opened it up, folding the keyboard behind the screen the screen is stuck in landscape mode.   The only method ive found to change its orientation is to go to desktop and run the intel graphics app to edit the orientation.
    Combined this makes the slim keyboard worse than useless in several usage scenarios.   I want the slim keyboard for the occasional need to input more data than is practical on the touch screen AND to protect the tablet.... but if your usage is more tablet than notebook you will find yourself constantly working around these limitations.   
    You have a great product here, but you really need to take a page from the surface playbook here.   They kind of set the standard and expectations for how keyboard covers on tablets should work and while I really like the hardware the usage is awkward as it stands. 

    Just got our first Venue 11 into the office and was very disappointed to find this thread already active.  Yes, this is a very simple use-case where someone will have the slim keyboard connected and then flip it back to use the onscreen keyboard for the modern UI.  Auto screen rotation and pop-up onscreen keyboard really are a must when the keyboard is flipped back.  Not sure how that very basic behavior could have been missed in testing.  Hoping for a resolution soon...

  • Open letter to Cisco regarding the UC320 platform

    Cisco,
    I have never in my life been exposed to a "production" piece of equipment with so many bugs, missing features and oddities as the UC320. While I am sure many of you are working hard to reign in the problems, this platform is an utter embarrassment that should be in the preliminary alpha stages, not a channel product being sold to end users.
    It is clear that Cisco has little understanding of how SMALL business works and how SMALL partners work with small business customers. A larger partner may be able to string a larger business along with promises of bug fixes and feature additions while charging them to make things right and.or padding the overall cost to account for the callbacks. True small businesses don't have the time, patience or money to deal with problematic hardware. When a partner sells a small business a piece of technology, it better work (at a reasonable cost) or the technology and the partner are out the door.
    I was extremely excited when this system was announced and saw great potential for small business customers and an alternative to the Avaya Partner IP and other platforms targeted at the same demographic. I jumped in and put a UC320 in the office of one of my small customers. This whole experience has cost me the trust of a client and is going to end up costing me $3000-$4000 out of pocket (hardware, labor, travel) to make things right with the customer.
    As it stands, countless hours have been spent trying to get this system to operate in a reasonably stable and productive manner. At this time the UC320 system has been reset and reconfigured in KEY mode (this time using 2.1.3(0), as the problems with steering digits, call routing and redial in "hybrid mode" made the system more than a little cumbersome to use. Now in KEY mode, caller ID only works on some stations AFTER a call is picked up. On one station, incoming calls are somehow routed to the "Phone Monitor" buttons instead of the "Shared FXO Line" buttons. The user has to press the monitor button to pick up a call, but the call does not always ring at the station so she has to watch for the lights. While the caller ID functionality is a bit better after the latest firmware update, it is still far from working properly. These basic call routing problems are not reasonable and not acceptable, period. The customer is tired of "we are working on it" and so am I.
    Other problems (to mention a few):
    The GUI is full of buggy behavior. One example if many: The impendence matching dialog only works the first time around and then the GUI loses track of what it is doing and must be reset.
    It takes 7-10 minutes for the GUI to load to the login screen over a remote connection. The UC320 is connected to a Verizon DSL, while not blazing fast it is a decent connection. Initial GUI loading on the LAN is almost as bad.
    The IE9 product that ships with every new Windows computer is not compatible with the GUI. This is not reasonable.
    The AA is somewhat unpredictable with regard to picking up calls and sometimes results in a busy tone and dropped call, even if the call is the ONLY call on the system. Sometimes the prompts are garbled and sometimes the AA does not even pick up.
    Steering digit redial issue - still not addressed. Redial on hybrid mode is useless, as is the phonebook.
    Caller ID only works part of the time, yet on every other system I have ever used, it works 100% of the time. This is not acceptable.
    Answered calls on shared FXO lines show as MISSED on other stations with those lines. The workaround: remove the missed calls display feature. This is not acceptable.
    Thus UC320 is not happy unless it is the only router, DHCP and DNS client on the LAN. The grayfield implementation appears to fail no matter what LAN topology and equipment are used. This device is far from friendly to the typical SBS or existing LAN with a dedicated DNS and/or DHCP server.
    The handsets have a cheap feel to them compared to the Avaya and other competitors phones.
    The sound quality of the ringtones is almost laughable if not sad
    The speakerphone quality and overall voice quality are not as good as the competition's.
    The filtering functionality of the logging feature does not appear to work properly
    Firmware updates often result in a HANG condition where either the GUI needs reset, the system needs a physical reset and/or sometimes defaulted
    Firewall port forwarding rule oddities where a rule is deleted from the gui but is still active in the firewall, yet the inability to easily use another data router to work around this problem.
    The inability of the device to properly use the LAN port for INTERNET based functionality (Time for example) if the WAN port is NOT connected,
    countless other 'issues" raised in the support forum and other venues...
    These are ALL very basic functions that one would expect to be fixed BEFORE a basic telephone system platform is released for production. It is absolutely unreasonable for a CUSTOMER to have to put up with a system this buggy and it is absolutely unreasonable for a partner to have to devote this much time and money to getting system to work at even a very basic level of functionality.
    To repeat the scenario: This config is as basic as it gets running 2.1.3(0) with (3) system phones, (3) users, (2) pots trunks and that's it. There are no odd call routing scenarios, no complex AA rules or schedules (in fact the AA is defaulted, including prompts). All (3) system phones have BOTH shared FXO lines (KEY MODE). Each and every firmware version has been tried and the system has been defaulted numerous times. The system fails to meet even the most basic expectations of myself or the end user and has become a sore spot between our company and a very good client.
    I am somewhat baffled, if not outright bothered by the fact that this device is riddled with so many problems and the fixes are taking so long to be implemented, if at all. I have been asked (ordered) by the customer to get this "hunk of crap" out of their office and replace it with something that works "at no additional cost". I could not agree with the customer more...
    A very unhappy Cisco Partner.
    William Burnett

    To William (and Cisco,)
    Honestly, I like Cisco.
    I like their  "openess" (you can find documentation and help on almost anything  anywhere), the contribution they make to industry by their huge R&D  effort (more than all their competition combined....or so I've been  told...), the accessibility and responsiveness of some of their key  people in the distribution channel, and yes, I like the ecosystem in  terms of support, tons of free education and sales support for both  their SMB and classic enterprise solutions.
    Having said that, I thank God for people like William  Burnett, who I am sure opened the eyes of many partners about the things  that are horrendously wrong with some of the products in the SMB  portfolio, most notably the UC320. I think it is fair to say, that  William has effectively "killed" it (the UC320) in it's present  incarnation. That is, unless Cisco, decides to really rise to the  challenge and fix a product that at first seemed ideal for the small  enterprise, but which was poorly implemented in terms of QC and in some  cases design.
    We certainly are not going to be touching the UC320  with a 10ft pole now Nobody wants (or can afford to) get a bad name by  selling "trouble" to your Mom&Pop shops or to people whose trust you  worked hard to gain and who are really depending on you to deliver. Not  in this economy....not ever.
    Coming from a Nortel telephony background, its really  hard to accept that having to respond to trouble calls or complaints  continuously from customers when Nortel products worked so reliably. In  fact, Nortel Norstar is so reliable as a key system that people joke ,  that's why they went out of business, they couldn't generate enough  turnover in new sales on account of people holding on to their Norstar's  forever.
    As a seller/installer/user of Cisco voice (UC540) and CME there are a couple recommendations I would like to make to Cisco:
    1)Private line emulation - inability to transfer or conference calls on a private line.  (using the TRUNK XX command) on the CME/UC500 platforms needs to be  significantly improved in order to keep up with the competition:
    for  one, when you select a private line and make a call you cannot transfer  that call. Every other system I have worked with allows you to do this.  This for me is a glaring "defect/design flaw". I spent a lot of time  trying to get this "fixed" as I couldnt believe that Cisco would just  omit such a basic function when all their competition  has it. (You dont  even think about this when dealing with other systems.) Its just  expected.
    2)Private line emulation - Inability to reflect the dialed number in the Call Detail Records for calls made via a "private line". If you select a private line on the UC500 or  CME and make a call, the dialed number would not show up in the CDR. I  have programmed systems from Nortel (Norstar, BCM,CS1000), Avaya - (IP  Office 500, Partner Plus, and S8x00 Communication Servers) as well as  various systems from Mitel and
    Panasonic .  The CDR packages for these systems are very well implemented and  documented. Cisco's systems are well documented as well, but this is an  area of the implementation where Cisco falls behind the competition. I am sure this can be fixed, but for some reason, despite a number of requests, it hasnt.
    In  trying to understand why it is Cisco, with such a huge R&D budget,  can't seem to get some things working properly that the competiton has  long ago solved and moved on with, I have come to the conclusion that it  must be that Cisco propably didnt tap enough of the right (human)  resources when it was developing its voice portfolio, and the lack of  industry experience shows up in some random places. Sad to say, not  paying attention to some of these details, to real world usage  scenarios, makes what would be an otherwise super product, just good  enough.
    Cisco is the biggest networking vendor on  the planet. People have a right to have high exectations of Cisco. Their  marketing also conditions users and partners to expect more when using  their solutions. While we accept that no one is perfect, not even the  mighty Cisco, I think most of the complaints and dissapointment  expressed in this forum, on this particular thread, are justified  because there is a strong feeling that if Cisco can be such a  trailblazer with their enterprise portfolio, that they should have  understood the importance of ensuring and enforcing good quality control  in the design and manufacture of the SMB portfolio. I honestly hope  someone from "Corporate" or high enough to make a differnce, looks at  this thread started by William and uses it to inspire the will to fix  what needs to be fixed to redeem the UC320 in whatever incarnation, in  the eyes of its partners (even former ones....such as William)and  customers. This is beginning to look like a textbook case of how not to  do product development.
